Best settings for 200.000 pages/day

Apache server performance tuning

[fauzzo]

Hi,

I am running a lot of PHP code and mod rewrites on a Apache 2 web server, it has about 200.000 page views each day, and I got errors like these:

[error] server reached MaxClients setting, consider raising the MaxClients setting

Allowed memory size of 8388608 bytes exhausted (tried to allocate 0 bytes)

[alert] (11)Resource temporarily unavailable: setuid: unable to change to uid: 65534

I am using default settings, should I change something? Which are appropriate values?

Thanks a lot!
